Capacity & Compatibility

This 768GB kit contains six 128GB DDR5 4800 CL40 ECC RDIMM modules built for SuperMicro X13SEM-F and X13SEM-TF servers. Registered buffering and on-die ECC protect data integrity in multi-socket workloads. The 288-pin form factor matches the platform's memory slots exactly.

Sustained Load Behaviour

Modules run at 1.1V with Samsung, Micron or Hynix DRAM and are stress-tested under load before shipping. The 4Rx4 organisation spreads traffic across ranks, helping maintain throughput during long compute or virtualisation sessions. Registered signalling reduces electrical load on the memory controller.

Upgrade Context

The kit replaces lower-capacity RDIMM sets or fills empty slots on X13SEM-F and X13SEM-TF boards to reach the platform maximum. The jump is worth it when memory pressure limits VM density, in-memory databases or large dataset processing. No heat spreaders are fitted, so airflow must follow the server vendor's guidelines.

Questions sur cet article

How much heat does the 768 GB kit generate when the server runs continuously at 4800 MT/s?

Each 128 GB RDIMM operates at 1.1 V without a heat spreader, so total power draw scales with six modules under sustained DDR5 4800 load.

What must the SuperMicro X13SEM-F or X13SEM-TF already have to accept this 6 x 128 GB kit?

The board needs six free 288-pin DDR5 RDIMM slots and a BIOS that supports 4Rx4 registered ECC modules at PC5-38400 speed.

Will these CL40 4Rx4 modules work alongside any existing DDR5 RDIMMs already installed in the same server?

Mixing is possible only if the installed DIMMs are also DDR5 4800 ECC registered 4Rx4 at 1.1 V; otherwise the memory controller will down-clock or disable the mismatched ranks.
